What is FlexRAN? • Flexible Radio Access Network (Wireless Base-station running on Intel Architecture - IA) • Scalable, flexible Hardware + Software platform with optional Hardware acceleration for RAN functions (PHY, MAC, RLC/RRC, PDCP) 8 Wind River Linux OS/KVM – Low Latency Real Time VM VM VM Open API Wireless Access L1 Reference + Open API Wireless Access RLC, MAC Open API Wireless Access PDCP COTS Hardware Platforms – single or multi HW instance VM Open API S-GW VM Open API P-GW VM Open API MME VM Open API MEC Apps, OSS/HSS/PCRF, etc Virtual Network Functions (VNF) - L1, MAC/RLC, PDCP – RAN - SGW, PGW, MME, etc - EPC - MEC Apps and Services - Scale VMs based on capacity, deployment scenarios and overall performance COTS Hardware platform with FPGA Hardware acceleration e.g. - L1 processing offload [FFT/Turbo] - CPRI termination - DataPath – IPSec, vSwitch Programmable Radio Frontend – Either CPRI over IP, or native CPRI. Architecture consistent with future Radio over Ethernet FlexRAN (Radio Access Network) EPC (Enhanced Packet Core) MEC CPRI 10/25 GbE Remote Radio Heads (RRH) Software and workloads used in performance tests may have been optimized for performance only on Intel microprocessors. Performance tests, such as SYSmark and MobileMark, are measured using specific computer systems, components, software, operations and functions. Any change to any of those factors may cause the results to vary. You should consult other information and performance tests to assist you in fully evaluating your contemplated purchases, including the performance of that product when combined with other products.
